In modern biscuit production lines, automation is not only reflected in forming, baking, and packaging stages but also plays a crucial role in the front-end raw material handling process. To solve the challenges of low manual feeding efficiency, severe dust pollution, and inaccurate weighing, the Automatic Flour Feeding and Weighing System has been developed. This system ensures precise and efficient flour delivery, providing stable and reliable support for biscuit production.
The system mainly consists of two core components: the Dust-Free Flour Feeding Machine and the Weighing Hopper. Together, they achieve a complete closed-loop control process, from flour feeding, screening, conveying, and precise weighing to automatic discharging into the mixer.
Workers pour bagged flour, sugar powder, or starch into the feeding station. The material is sieved through a vibrating screen, then enters the conical hopper. With the assistance of negative pressure, the flour is conveyed into the buffer silo or weighing hopper.

The weighing hopper receives preset weight commands from the HMI based on the mixing requirements. Flour is sucked into the hopper through negative pressure. The load cell monitors the weight in real time. Once the target weight is reached, the system stops automatically and discharges the flour into the mixer.
